The spread of Ash dieback threatens out native population and it is through understanding and adapting that we can limit its effect on the forestry sector. Four years later she found a tree that was resistant to the disease and named it Betty which was used to help identify three genetic markers associated with resistance against the disease. Use our guide to learn how to spot the key signs.
Edwards was the first person to identify Ash Dieback, caused by the fungus Hymenoscyphus fraxineus, discovering it in Ashwellthorpe Woods, Norfolk in 2012.
